All commercially grown artichokes in the United States come from California, particularly the central coast where cool summers and mild winters provide an ideal growing area. The globe artichoke, a member of the composite family of flowers, is closely related to the thistle. If left to flower, the plants produce violet blossoms measuring seven inches across. The part we eat is from the immature flower bud. The edible portion of the "globe" is composed of the fleshy bases of the flower bracts (look like leaves) and the receptacle to which the bracts are attached, commonly referred to as the "heart." Artichokes can be purchased all year long, but the best quality are available from March through May. Select artichokes that are dark green, heavy for their size and blemish-free. The globe should be compact and not beginning to open. Artichokes can be washed, placed in a plastic bag, and stored in the refrigerator for several days until used.
